Hybrid batteries will not stay charged. Dealer said it was the either generator or alternator that keeps these batteries charged and the cost would be $ 2400+.
What is the need for this repair and is
This cost valid?

The power steering line connected to the power steering pump may have a nut that has loosened, possibly causing a power steering fluid leak. If the fluid contacts the hot exhaust components, a fire could start. Dealers will inspect the nut and tighten it. If a fluid leak is found, the fluid level will also be checked. The recall began September 26, 2008. The GM recall number is 08284.

I have had good performance from this vehicle up to about two months ago the hybrid drive indicator light came on and shut down.
The code "pia5a" indicates a battery problem. I am currently trying to locate a facility to get it repaired.
